16 Claims.

Our invention, which relates to ice Crushers, will be best understood from the following description when read in the light of the accompanying drawings of an embodiment thereof, the scope of which invention will be more particularly pointed out in the appended claims.

In the drawings:-

Fig. '7 is a plan Vof the rocker member according to Fig. 5, with parts omitted;

Fig. 8 is a detail as viewed on the line 8-8 of Fig. 7; and

Fig. 9 is a section on showing a detail.

Referring to the drawings, the ice crusher comprises a casing I having an upper opening 3 for receiving the ice to be crushed and a lower opening 5 for discharging the ice after it is crushed.

At the interior of the casing are spaced plates 1, 1 the upper edges of which are welded to the lower portions of the side walls 9 of the neck of the casing, these members projecting vdownwardly into the body of the casing to forma receptacle or hopper II for receiving the ice. The lower the line 9 9 of Fig. 1,

I opening of the hopper I I is partially closed by an ice crushing instrumentality,comprising a pair of rocker members adapted to act upon and crush the ice which passes between the opposed surfaces I3 thereof, and to feed the crushed ice toward the lower opening 5 of the casing.

As shown, the rocker members are mounted upon shafts I5 supported at opposite ends in the opposite side walls I1 of the casing. Pivotally mounted upon these shafts I5 are handle members I9, which lie in the same vertical plane and extend through narrow members and narrow slots 23 in the casing to the exterior of the latter, so that the handle members may be oscillated to oscillate the rocker members. It will be observed that the slots 2l in 5 the rocker members are of length greater than the width of the handle members so that there is lost motion between the handle members and the rocker members. This construction enables a hammer blow to be imparted by the handle members to the rocker members, which is effective readily `to break up the ice.

As shown, the openings 25 at the lower ends of the handle members, through which openings the shafts I5 extend, are of oval or elliptic shape with their major diameters extending lengthwise of the shafts, so that the handle members have a lost motion connection to the shafts causing the handle members to move vertically relative to the casing when the operator grasps the grip portions 21 of the handle members and raises the device off a table or other support. This lost motion is eifective in the present device for operating a readily releasable means for locking the handle members in their positions shown by Fig. 1 when the device is placed in vertical position upon a support. For this purpose the handle members are shown as formed with lateral hooklike projections 29 adapted to hook over the edge of the upper opening 3 of the casing when the device is placed upon the support. When the grip portions of the handle members are grasped by the operator and the device raised from the support the hook-like members will automatically disengage and will not reengage until the device is again placed upon the support and the handle members moved into their positions shown by Fig. 1.

As best illustrated by Fig. 1, the rocker members project at their outer sides through openings 3| in the casing. These rocker members, as shown, are hollow, each having an outer or rear wall 33, and, formed integrally with the rear Wall, a top wall and opposite side walls 37, the top wall and side walls being formed by bending over portions of the sheet `of metal which forms the rear wall. Pivotally connected to the body portions, just described, of the rocker members are portions 39 to which are welded arms 4I the outer ends of which latter are bent to form portions 43 in adjustable sliding engagement with the inner surfaces of the rear walls 33 of the' body portions. As illustrated, the rear walls 33 are provided with dumb-bell-shap-ed slots slots 2| in the rocker 45 through which extend the screw-threaded 55" shanks 41 of set screws 49, these shanks being screw-threaded into the portions 43 of the arms 4I. By this means the portions 43 of the arms can be slid upwardly from their position shown in Figs. 1 and 2 to their position shown in Fig. 3, so as to swing the portions 39 of the rocker members relative to the body portions thereof. As shown, the set screws 49 have portions 5I adapted to enter the enlargements 53 at the upper and lower ends of the dumb-bell-shaped slots 45,7so

as securely to lock the portions 43 of the arms 4I 1 in their adjusted positions. As illustrated, three positions of adjustment corresponding to three different degrees of iineness of the crushed ice are provided, namely, the positions shown by Figs. 1 and 3 and an intermediate position secured by having one of the set Screws 49 at the upper end of its slot 45 and the other set screw at the lower end of its slot.

As shown, the parts 39 of the rocker members are provided with downturned ears 55 thro-ugh which extend a pin 51 pivotally connecting said parts to the body portions of the members, these pins at their opposite ends being supported by the opposite side members 31 of the bodies of the rocker members. For strengthening the parts, the corners of the top members 35 of the body portions of the rocker members arebent downwardly to form ears 59 which have perforations 6I through which the pins 51 also extend. As illustrated, the side member 31 of the body cf each rocker member is provided at opposite sides thereof with a downwardly projecting portion 63, the extremity of which is bent at right angles to form a stop 65 which cooperatesk with the casing portion 61 when the parts are in the positions illustrated by Figs. l and 3. The opposite edges of each side member between the shaft I and rear wall 33 are notched, as indicated at 69, by slitting said side members and bending the portions between the slits at right angles, these bent portions forming stop members 1I which engage with the lower edges of the adjacent openings 3I in the casing whenthe parts i are in the positions shown by Fig. 2; Thus the cooperate with the stop members 65 andv 1I casing to limit the travel of the rocker-members in opposite directions.

As shown, each rocker member is provided at4 its uppermost portion with a row of large teeth 13. These teeth have openings-permitting them to be threaded on the shafts I5, and extend radially of the shafts through openings 'I5 in the bars 4I and openings 'I1 in the top walls 35 of the bodies of the rocker members. By this construction when the rocker members are oscillatedby the handle members the teeth move with them.

Four of such teeth are shown for each rockerv member, and it will be observed from Figs. 1 and 4 that in the present device the outer'pairY of teeth of the row are shaped to have their ice engaging points 19 in a higher plane than the ice engaging points 8I of the middle pair of teeth.

These teeth act to split the ice entered into vthe hopper I I, and it has been found that by having the ice engaging points of some of the teeth in a lower plane than the ice engaging points of other teeth clogging of the ice between the several teeth and between the latter and the casing is prevented. For example, if a cube of ice is entered into the hopper, the ice engaging points 8|, when the handle members are oscillated, will break off a pair of opposite edge portions of the cube on the first closing stroke of the rocker closing stroke of the rocker members the ice engaging points 19 will engage opposite sides of the cube toward its center and break up the remaining portions. Were the ice engaging points all in the same plane there would be a tendency for the cube to be split into flat sheets which would tend to clog between the teeth, and between the outer teeth of the row and the adjacent walls of the casing.

As shown, the plates 1 forming the side walls of the hopper II are cut away, as best shown at 83 in Fig. 4, to permit passage of the teeth 13 into and out of the hopper. When the parts are in the position shown by Fig. 2, ice may be entered into the hopper to rest against the rocker members, the teeth 13 then being outside the hopper. When the parts are moved into the posistruck up to provide teeth 85 which are smaller than the teeth 13, and these teeth act to divide the ice as it passes. between the rocker members and to feed the ice downwardly between said members so that the crushed ice will be discharged through the lower opening 5 of the casing. Although but one of the rocker members need be provided with teeth 85, it has been found that best results will be secured by providing one of the members 39 at its upper portion with several rows of teeth, as illustrated, the toothless lower portion of this member 39 being bulged, as indicated at 81, toward the other rocker member so as to provide less clearance between the rocker members a-djacent that toothless portion. By having fewer teeth on one member than on the other, and preferably no teeth at at least the lower portion of one of the members, the device acts to prevent clogging of the ice between the two members. Commonly if both members 39 were provided with teeth throughout their entire extent the ice would clog between said teeth.

It will be understood that within the scope of the appended claims wide deviations may be made from the form of the invention illustrated and described without departing from the spirit of the invention.
